<p>The <a class="link" href="mapped_view.html" title="Class template mapped_view">mapped_view</a> class simplifies mapping host-memory to a compute device. This allows for host-allocated memory to be used with the Boost.Compute algorithms.</p>
<p>The following example shows how to map a simple C-array containing data on the host to the device and run the reduce() algorithm to calculate the sum:</p>
